0 votes 0 votes Destination Unreachable is an Error handling (or feedback message) and not an echo request-reply type of ICMP. Therefore, ICMP is just a courtesy message from router to sender. It is upon the sender as to how it responds to it. Thus, the most likely case would be that the sender will discard the original packet.
